Here are the links to the MINI factory alternators, or lower cost aftermarket alternators. You will need to match your alternator to the diagrams to see which one you have.

Here is the factory replacement serpentine belt and here is an aftermarket belt.

Thank you all for your help.  So it turned out to be alternator related....battery died after a new one went in, check engine light went on. It was the alternator all along swapping out the serpentine belt and alternator. Both are Duralast. I wanted to go Bosch but it wasn't in stock and unfortunately I could not go beyond today without my car running so fingers crossed it lasts the duration of me keeping this Mini. Thankfully I was able to jump start it yesterday by my job where it died and gave it enough juice to get home without the battery light even going back on. Hoping to have that done today!

That would be the best case scenario.

Yes, you are correct. Didn't know the car was still idling fine..

As others have mentioned, possibly clutch related or maybe something with the axle?

Good luck with the diagnosis, hope it is nothing serious.

an idler pulley (tensioner) bearing failure is a common cause of the clanging and banging noise and failure of proper tension on the belt.

Some people say whenever one changes the serpentine belt ( say at 100,000 miles) that the idler pulley should also be changed no matter what.

This is easy to check by taking tension off of the belt (or removing it) and spinning the pulley. If bearings not smooth as silk, then bingo

"replaced" does not mean "replace correctly"

Hope you get a good diagnosis.

Hey Dan, thank you for the response, it is 6-speed manual, clutch was replaced at close to 115K miles, while of course nothing can be ruled out until diagnosed, given the clutch was replaced recently probably not the situation....good God I hope not.

Does your car have a fully manual transmission and clutch?
The only thing I could relate your description to was way back around 1967: my Dad's 1964 Ford 6 cylinder with  a "3-in-the-tree" (column shift) manual transmission. When its clutch wore out, the lining came loose from the clutch plate and flapped around in the bell housing, it made a noise something like that.

.

This is my third mini so I know a lot about the nuances but this in uncharted territory for me.

Can anyone provided insight or share a personal experience on this?

It 'sounds like' the serpenting belt let go. Let us know what you find out.
